PGC Statement No. 5
NATIONAL FUEL GAS DISTRIBUTION CORPORATION
PENNSYLVANIA PUBLIC UTILITY COMMISSION v.
NATIONAL FUEL GAS DISTRIBUTION CORPORATION (PURCHASED GAS COSTS -- 66 PA.C.S. SECTION 1307(1)),
DOCKET NO. R-2013-2341534
DIRECT TESTIMONY OF KAREN M. SNYDER R-2013-2341534
1 Q. Please state your name and business address.
2 A. My name is Karen M. Snyder and my business address
3 is 6363 Main Street, Williamsville, New York 14221.
4 Q. By whom are you employed and in what capacity?
5 A. I am employed by National Fuel Gas Distribution
6 Corporation ("Distribution") as a Rate Analyst in the Rates and
7 Regulatory Affairs Department.
8 Q. Will you state briefly your educational background and
9 experience?
10 A. I graduated from Niagara University, in May 1994, with a
11 Bachelor of Business Administration degree in Accounting.
12 Prior to joining Distribution, I worked in public accounting for five
13 years and earned my CPA license in NYS in 1998. I gained an
14 additional four years of industry based financial analysis
15 experience before joining Distribution in 2003.
16 In July 2003, I was employed by Distribution in the Financial
17 Accounting Department. In May 2006, I transferred into the
18 Rates and Regulatory Affairs Department. I was promoted to
19 my present position of Rate Analyst IV in March 2009.
20 Q. Please summarize your responsibilities in this position relative
21 to this proceeding.

DIRECT TESTIMONY OF KAREN M. SNYDER R-2013-2341534
A. My responsibilities include preparation of filings relating to recovery of
2 gas costs. Therefore, I am familiar with the Pennsylvania Public Utility
3 Commission's ("Commission") procedures for gas cost recovery.
4 Q. What is the purpose of your testimony?
5 A. I am testifying in support of PGC Exhibit Nos. 17 and 23 and PGC
6 Exhibit Nos. 1, 2, 3, 21, 21-A, 21-8 and 21-C.
7 Q. Please explain PGC Exhibit No. 17.
8 A. PGC Exhibit No. 17 compares Distribution's average transportation
9 and storage costs from its affiliates to those from others upstream of
10 the affiliates for the twelve months ended November 30, 2012.
11 Q. Does PGC Exhibit No. 17 address any other matters?
12 A. Yes, it addresses any purchases of gas Distribution may have made
13 from its affiliates. As detailed in PGC Exhibit No. 17, and explained
14 further in PGC Exhibit No. 19, pursuant to its tariff, Distribution made
15 purchases of monthly imbalance gas totaling 112,642 Mcf at a unit
16 cost of $2.5496/Mcf from an affiliate during the twelve months ended
17 November 30, 2012.
18 Q. How does the Pennsylvania Division's affiliated average cost of
19 transportation services compare with others?
20 A. As shown in PGC Exhibit No. 17, Page 2, Distribution's average
21 transportation costs from National Fuel Gas Supply Corporation
Page 2 of29
DIRECT TESTIMONY OF KAREN M. SNYDER R-2013-2341534
1 ("Supply") compare favorably with costs of transportation from
2 Columbia Gas Transmission LLC, Tennessee Gas Pipeline Company
3 and Texas Eastern Transmission LP. It is imperative to emphasize,
4 however, that transportation services by the interstate pipelines
5 upstream of Supply are not interchangeable with transportation service
6 provided by Supply. Specifically, Supply provides the benefit of a
7 multiple point system that distributes the gas from the applicable
8 upstream pipeline receipt points to Distribution's many local distribution
9 systems that in turn deliver gas to end-user customers.
1 o Q. What is the benefit of using Supply's storage service?
11 A. Supply provides the no-notice storage service that is critical for
12 meeting Distribution's temperature sensitive demand. It also allows for
13 overrun service from time to time and offers a more flexible
14 injection/withdrawal operation than the storage services provided by
15 other upstream pipelines.
16 Q. Does the cost comparison in PGC Exhibit No. 17, Page 3 represent all
17 the costs associated with storage services?
18 A. No. The comparison does not represent all the costs incurred when
19 Distribution contracts for storage capacity with upstream pipelines. In
20 reality, most storage agreements require Distribution to sign up
21 specific transportation service to move gas into and from the storage
Page 3 of 29
DIRECT TESTIMONY OF KAREN M. SNYDER R-2013-2341534
1 field. This additional storage transportation cost is incremental and
2 should be factored in the storage cost comparison. In contrast,
3 Supply's storage service is more economical because Distribution
4 contracts with Supply only for sufficient transportation service to meet
5 customers' peak day and seasonal requirements. No additional
6 transportation capacity is required to use Supply's storage.
7 Q. Please briefly explain PGC Exhibit No. 23.
8 A. PGC Exhibit No. 23 has three schedules, which contain Distribution's
9 projected purchased gas cost portfolio. The schedules are:
1 o • Schedule 1:
11 o Projected upstream transportation volumes at Distribution -
12 PAD's citygate (pages 1-2).
13 o Upstream transportation service tariff rates (pages 3-4)
14 o Storage and purchased gas costs (pages 5-6).
15 o Storage volumes (pages 7 -8).
16 o Summary of storage unit costs (pages 9-10).
17 o Storage costs (pages 11-12).
18 o Storage unit costs (pages 13-14).
19 • Schedule 2: Distribution- PAD's Appalachian and local production
20 gas cost calculation.
21 • Schedule 3: Upstream pipeline contracted capacity and rates.

DIRECT TESTIMONY OF KAREN M. SNYDER R-2013-2341534
1 Q. How is the projected purchased gas portfolio generated?
2 A. The projected purchased gas portfolio, in terms of receipt and
3 delivered volumes, is generated from the SENDOUT™ model.
4 Q. Please briefly describe the SENDOUT™ model.
5 A. The SENDOUT™ model is a linear programming computer model that
6 is used by the Gas Supply Administration Department. In essence, the
7 model identifies the optimal suppliers to use each month and how to
8 schedule purchases from such suppliers. It also determines, for the
9 Pennsylvania Division, storage injections, withdrawals and resulting
10 levels of inventory to meet the system demand on a least cost basis.
11 The optimization process considers numerous factors which include,
12 but are not limited to, daily flow constraints, storage injection and
13 withdrawal flows, daily and seasonal pipeline flow constraints, storage
14 inventory limits and ending targets, gas supply costs, transportation
15 costs and shrinkage, the time interval to be optimized and the market
16 requirements.
17 Q. How is the gas cost in PGC Exhibit No. 23, Schedule 1, Pages 5 and 6
18 calculated?
19 A. With a few exceptions, the gas cost is calculated by multiplying the
20 receipt volume in PGC Exhibit No. 23, Schedule 1, Pages 1 and 2 by
21 the projected wellhead price in PGC Exhibit No. 25. The forecasted
Page 5 of 29
DIRECT TESTIMONY OF KAREN M. SNYDER R-2013-2341534
basis is also applied to the receipt volume and the basis applied is
2 dependent upon the receipt and delivery points. The exceptions are,
3 as discussed in PGC Exhibit No. 8, Distribution's contracts for some
4 gas supplies with fixed prices or limited price escalations to be
5 delivered during the period December 2012 through March 2013.
6 These gas supplies are individually priced in accordance with their
7 negotiated agreements. The gas costs presented on PGC Exhibit No.
8 23 reflect these exceptions.
9 Q. What are the sources of the upstream pipeline rates in PGC Exhibit
1 o No. 23, Schedule 1, Pages 3, 4, 9 and 1 0?
11 A. The rates are derived from the latest tariff filings. The specifics of
12 each pipeline are discussed below:
13 • Columbia: The current rates, which were taken from Docket RP12-
14 605-000 Operational Transactions Rate Adjustment Filing, Docket
15 RP12-000 Annual Retainage Adjustment Mechanism Filing and
16 Docket Nos. RP95-408 and RP12-261-000 Annual Environmental
17 Rate Adjustment Filing, are assumed to remain in effect throughout
18 the projection period.
19 • Tennessee: The current rates, which were taken from Docket Nos.
20 RP11-1566, RP11-2066 and RP12-450, are assumed to be in
21 effect throughout the projection period.
Page 6 of 29
DIRECT TESTIMONY OF KAREN M. SNYDER R-2013-2341534
1 • Supply: The current rates, which were taken from Docket No.
2 RP12-88-000, are assumed to be in effect throughout the projection
3 period.
4 • Texas Eastern: The current rates, which were taken from Docket
5 RP-13-237 -000 Annual ASA and Interruptible Revenue
6 Reconciliation Report are assumed to be in effect throughout the
7 projection period.
8 Q. Please describe Distribution's FY2013 and FY2014 storage rate
9 derivation in PGC Exhibit No. 23, Schedule 1, Pages 13 and 14.
1 o A. Distribution's Pennsylvania Division's storage rate derivation mirrors
11 the calculation actually performed at the ,end of each fiscal year. The
12 annual gas costs inclusive of commodity and demand purchased gas
13 costs, upstream transportation costs and storage rental costs are
14 totaled. The cost of gas purchased for off-system sales is excluded
15 from the storage rate calculation. The net cost is then divided by the
16 annual gas delivery volume at Distribution's Pennsylvania Division
17 citygate.
18 Q. Please explain PGC Exhibit No. 23, Schedule 2.
19 A. PGC Exhibit No. 23, Schedule 2 is Pennsylvania's Appalachian
20 Production ("~P") and Local Production ("LP") volume and cost
21 summaries. AP is production received directly by Supply and
Page 7 of 29
DIRECT TESTIMONY OF KAREN M. SNYDER R-2013-2341534
1 transported by Supply to Distribution whereas LP is production
2 received directly by Distribution without the use of Supply's facilities.
3 Effective in this 1307(f) filing, Distribution has two AP Production
4 Rates. AP Production Rate 1 is priced at the forecasted wellhead rate
5 plus a monthly adjustment. The monthly adjustment is a composite
6 rate that reflects that approximately 33% of the AP is purchased
7 pursuant to spot contracts that are priced at 80% of the Appalachian
8 Index and 67o/o is purchased pursuant to dedicated (Life-of-Reserves)
9 contracts that are priced at 1 OOo/o of the Appalachian Index. AP
1 o Production Rate 2 represents a one-winter contract that Distribution
11 entered into effective November 1, 2012. The contract is for 9,936
12 Dth/day of firm gas supply that is delivered into its Supply EFT
13 capacity. The price is the projected wellhead forecast plus the receipt
14 point differential at Columbia Appalachia less a $.03/Dth commodity
15 premium. Distribution also has one LP Production Rate this season.
16 LP Production Rate 1 is priced at the forecasted wellhead rate plus a
17 monthly adjustment. The monthly adjustment is a composite rate that
18 reflects that approximately 11 °/o of the LP is purchased pursuant to
19 spot contracts that are priced at 80°/o of the Appalachian Index and
20 89% is purchased pursuant to dedicated (Life-of-Reserves) contracts
21 that are priced at 100% of the Appalachian Index.

Q. Please explain PGC Exhibit No. 23, Schedule 3.
2 A. PGC Exhibit No. 23, Schedule 3 summarizes Distribution's contracted
3 capacity and rates by pipeline for the period December 2012 through
4 November 2014.
5 Q. Please describe PGC Exhibit 1.
6 A. PGC Exhibit 1 details, by month, for the twelve months
7 ended November 30, 2012, volumes and costs of gas
8 purchased from upstream suppliers, local production and
9 Peoples TWP, LLC ("T.W. Phillips"). The data shown in PGC
1 o Exhibit 1 represent historical information from Distribution's
11 books and records.
12 The category entitled "Upstream Purchases" on PGC
13 Exhibit 1, Schedule 1, Sheet 1 reflects Distribution's cost of
14 purchasing gas from various upstream producers, whose gas is
15 transported by long-line interstate pipeline companies to
16 National Fuel Gas Supply Corporation ('Supply"), which in turn
17 delivers the gas supplies to Distribution. A monthly breakdown
18 of Distribution's commodity and demand costs from upstream
19 suppliers is provided in PGC Exhibit 1, Schedule 1, Sheet 2.
20 Further detail of Distribution's costs from upstream suppliers is
21 provided in PGC Exhibit 1, Schedule 2, Sheet 1.
Page 9 of 29

12 The Demand cost of gas is split between Demand-
13 Natural Gas Supply ("Demand-NGS") and Demand-Distribution
14 Charge ("Demand-DC"). Demand-DC includes the cost of
15 pipeline capacity and storage needed to provide peak
16 delivery/temperature swing requirements for Distribution's sales
17 and SATC customers. These are costs that Distribution would
18 incur even if all customers converted to transportation service.
19 A certain amount of capacity would have to be maintained to
20 serve these peaking requirements. PGC Exhibit 1, Schedule 5
21 provides a detailed calculation of the Demand-DC costs.
Page 10 of 29
DIRECT TESTIMONY OF KAREN M. SNYDER R-2013-2341534
Demand-NGS includes the remaining demand costs incurred to
2 provide sales service. The Demand-NGS costs represent total
3 demand costs less Demand-DC costs.
4 Distribution shares Capacity Release Revenues on a
5 75%/25% basis. The transportation amount includes the
6 adjustment necessary to flow through 75% of these revenues to
7 ratepayers.
8 The category entitled "Transportation Credit" on PGC
9 Exhibit 1, Schedule 1, Sheet 1 reflects the costs recovered from
1 o transportation customers. A monthly breakdown of

1 Distribution's cost from T.W. Phillips is provided in PGC Exhibit
2 1, Schedule 3. T.W. Phillips is the only physical source of
3 supply for a small portion of Distribution's system. In order to
4 obtain other supplies Distribution would have to make a
5 substantial investment for the construction of new facilities to
6 physically connect a few existing customers to Distribution's
7 other sources of supply. The customers referenced are located
8 in Butler County, at the extremity of Distribution's system.
9 The category entitled "Exchange Gas" on PGC Exhibit 1,
10 Schedule 1, Sheet 1 reflects the recognition of gas costs related
11 to any monthly imbalances associated with tWo Exchange
12 Agreements as discussed in PGC Exhibit No. 8 and further
13 explained in PGC Exhibit No. 4. The monthly breakdown of
14 Distribution's costs associated with Exchange Gas is provided
15 in PGC Exhibit 1, Schedule 1, Sheet 6.
16 The category entitled "Off-System Sales" on PGC Exhibit
17 1, Schedule 1, Sheet 1 reflects costs of gas purchased for sale
18 to customers that are not part of Distribution's retail system.

PGC Exhibit 2 and PGC Exhibit 3 contain data pertaining
2 to projected volumes and costs of gas to be purchased by
3 Distribution. PGC Exhibit 2 contains projected data, by month,
4 for gas to be purchased from suppliers during the period
5 December 1, 2012 through July 31, 2013. PGC Exhibit 3
6 contains projected data, by month, for gas to be purchased from
7 suppliers during the twelve month period ending July 31, 2014.
8 Q. Please summarize how the projected data, contained in PGC
9 Exhibit 2 and PGC Exhibit 3, were prepared.
10 A. Based upon forecasted sales of gas explained by Ms.
11 Zablonski, Distribution determined the total volume of gas that
12 Distribution would be required to purchase in order to make the
13 projected level of sales to its customers. Volumes of gas that
14 Distribution would be able to obtain from local producers and
15 the small volume of gas to be purchased from T. W. Phillips
16 were projected. The remainder of gas supplies was projected
17 to be purchased from upstream suppliers.
18 Under FERC Order 636, Distribution is responsible for
19 the purchasing function previously provided by Supply. Supply
20 and upstream pipelines will transport this gas. PGC Exhibit 2,
21 Schedule 1 and PGC Exhibit 3, Schedule 1 summarize the

DIRECT TESTIMONY OF KAREN M. SNYDER R~2013-2341534
1 and PGC Exhibit 3, Schedule 5 provides data for the twelve
2 month period ending July 31, 2014.
3 Q. Please explain PGC Exhibit 21.
4 A. PGC Exhibit 21 is a computation of the projected cost of
5 purchased gas that would be included in rates effective August
6 1, 2013. This amount includes projected gas costs through the
7 end of the application period, July 31, 2014 and projected
8 over/under collections through July 31, 2013.
9 As indicated on PGC Exhibit 21, Schedule 1, Sheet 4,
10 the total projected cost of purchased gas per Mcf is $6.5457.
11 Of this amount, $4.6794 per Mcf is the commodity cost
12 (including the "E" factor), and $1.8663 per Mcf is the demand
13 cost (including the "E" factor).
14 The cost of gas has been separated into three categories
15 on PGC Exhibit 21, Schedule 1, Sheet 4: the Natural Gas
16 Supply Charge, the Gas Adjustment Charge and the Distribution
17 Charge.
18 For gas supplied to all classes of retail customers (except
19 those receiving service under load balancing service and
20 natural gas vehicle service rate schedules), the Natural Gas
21 Supply Charge is $6.5490/Mcf. This represents an increase of
Page 17 of 29
DIRECT TESTIMONY OF KAREN M. SNYDER R-2013-2341534
1 $0.4390/Mcf from the Natural Gas Supply Charge of
2 $6.11 00/Mcf included in rates from November 1, 2012 through
3 January 31, 2013.
4 For gas supplied to all classes of retail customers (except
5 those receiving service under load balancing service and
6 natural gas vehicle service rate schedules), the Gas Adjustment
7 Charge is ($0.2681 )/Mcf. This represents an increase of
8 $0.4852/Mcf compared to the Gas Adjustment Charge of
9 ($0.7533)/Mcf included in rates from November 1, 2012 through
10 January 31, 2013.
11 For gas supplied to all classes of retail customers (except
12 those receiving service under load balancing service and
13 natural gas vehicle service rate schedules), the Distribution
14 Charge is $0.2648/Mcf. This represents a decrease of
15 $0.0064/Mcf compared to the Distribution Charge of
16 $0.2712/Mcf included in rates from November 1, 2012 through
17 January 31, 2013.
18 In total, for gas supplied to all classes of customers
19 (except those receiving service under load balancing or natural
20 gas vehicle service rate schedules), the projected cost of gas is
21 $6.5457/Mcf. This represents an increase of $0.9178/Mcf from
Page 18 of 29
DIRECT TESTIMONY OF KAREN M. SNYDER R-20 13-2341534
1 the amount of $5.6279/Mcf included in rates from November 1,
2 2012 through January 31, 2013 for the recovery of purchased
3 gas costs.
4 The increase in rates for the recovery of purchased gas
5 costs results from a number of factors, one of which is an
6 increase in the "E" or experienced factor. The current "E"
7 factor reflected in rates as of November 1, 2012 is an
8 overcollection of $14,382,141 or ($0.7723)/Mcf 1. The projected
9 sales for passback of the "E" factor this period (TME July 2013)
1 o are 18,554,728 Mcf for Commodity and Demand - NGS and
11 21,264,051 Mcffor Demand- DC. As shown on PGC Exhibit
12 21, Schedule 1, Sheets 1-3, Distribution projects, through July
13 31, 2014, an "E" factor overcollection of $4,852,903 or
14 ($0.2651)/Mcf 2. The projected sales for passback of the "E"
15 factor this period (TME July 2014) are 18,335,882 Mcf for
16 Commodity and Demand- NGS and 20,721,402 for Demand-
2
Commodity: ($18,913,435) + 18,554,728 Mcf= ($1.0193)/Mcf Demand- NGS: $4,935,363 + 18,554,728 Mcf = $0.2660/Mcf Demand- DC: ($404,069) + 21,264,051 Mcf = ($0.0190)/Mcf
Commodity: ($3,883,552) + 18,335,882 Mcf = ($0.2118)/Mcf Demand- NGS: ($1,032,349) + 18,335,882 Mcf= ($0.0563)/Mcf Demand- DC: $62,998 + 20,721,402 Mcf = $0.0030/Mcf

DC. The projected overcollection produces an increase in rates
of $0. 5072/Mcf3.
The "C" factor rate also increased. The current "C" factor
reflected in rates as of November 1, 2012 is $119,539,221. The
projected sales for this period (TME July 2013) are 18,554,728
Mcf for Commodity and Demand-NGS and 21,264,051 Mcf for
Demand-DC. As shown on PGC Exhibit 21, Schedule 1,
Sheets 1-3, Distribution projects, through July 31, 2014, "C"
factor costs of $125,504,781 4. The projected sales for this
period (TME July 2014) are 18,335,882 Mcf for Commodity and
Demand-NGS and 20,721,402 Mcf for Demand-DC. The
change in the "C" factor results in an increase in rates of
$0.4106/Mcf.5 As shown on PGC Exhibit 21, Schedule 1, Sheet
1 this increase includes ($0.0075)/Mcf for the passback of
Where ($0.7723)/Mcf ("E" factor included in current rates) and ($0.2651)/Mcf ("E" factor included in projected rates); then ($0.7723)- ($0.2651) = $0.5072/Mcf.
$125,504,781 = $89,821,650 (PGC Exhibit 21, Schedule 1, Sheet 1, Commodity) + $30,398,042 (PGC Exhibit 21, Schedule 1, Sheet 2, Demand - NGS) + $5,424,569 (PGC Exhibit 21, Schedule 1, Sheet 3, Demand- DC)- $139,480 (PGC Exhibit 218, Sheet 2, Commodity- Storage).
$6.8108 (PGC 2013) less $6.4002 (PGC 2012 November 1) = $0.4106/Mcf. Where $6.8108/Mcf ("C" factor in projected rates)= ($120,219,692 + 18,335,882 Mcf)- ($139,480 + 18,335,882 Mcf) + ($5,424,569 + 20,721,402 Mcf) or $6.5565-$0.0075 + $0.2618, respectively /Mcf); and $6.4002/Mcf ("C" factor in current rates)= ($113,809,307 + 18,554,728 Mcf)- ($439,001 + 18,554,728 Mcf) + ($6, 168,915 + 21,264,051 Mcf); or $6.1337-$0.0237 + $0.2902, respectively /Mcf).

storage interest expense. The sum of the increase in the "E"
factor and the "C" factor represents a total increase of
$0.9178/Mcf [$0.5072 + $0.4106 = $0.9178].
PGC Exhibit 21, Schedules 2 through 11 explain the
derivation of Distribution's experienced over/under collection
factor ("E" factor) used in PGC Exhibit 21, Schedule 1.
PGC Exhibit 21, Schedules 4 and 10 detail refunds, by
component, received by Distribution, and these schedules also
calculate interest on each refund. There were no refunds
'received during the twelve months ended November 30, 2012.
Ms. Suarez will explain Distribution's proposal to reflect pipeline
refunds in current rates in her testimony.
The information provided above was derived on the
assumption that rates effective November 1, 2012 will remain in
effect through July 31, 2013. In all likelihood, the quarterly filing
for May 1, 2013 will adjust rates. The amount of net adjustment,
however, is not presently known.
Please describe the methodology used to determine the interest
rate that is applied to the over/undercollection of purchased gas
costs and storage injections/withdrawals.

The interest rate to be applied to the
over/undercollection of purchased gas costs and storage
injections/withdrawals is based on the Commission's Order at
docket number R-00072043. Under this methodology, the
Demand-DC component of purchased gas costs is calculated
separately from the other components of purchased gas costs
using the net over/undercollection for the twelve month period
ended November. The interest rate to be applied to
over/undercollections of Commodity and Demand - NGS
purchased gas costs is calculated based on the combined net
over/undercollection for both of these components for the
twelve month period ended November.
As shown in PGC Exhibit 218, Sheets 1-2, the interest
rate used in the storage interest calculation is determined on a
stand-alone basis using the twelve month period ending July,
per the Commission's Order at Docket number R-201 0-
2150861. The storage interest calculation is addressed under
the explanation of PGC Exhibit 21 B.
There was a net undercollection for the Demand-DC
component of purchased gas costs for the twelve months ended
November 30, 2012, as shown on PGC Exhibit 21A, Schedule

1 2, Sheet 2. Therefore, the interest rate of 6% was used to
2 calculate monthly interest. The projection for the twelve month
3 period ending November 30, 2013 is a net overcollection for the
4 Demand-DC component of purchased gas costs. Therefore,
5 the interest rate of 8% was used to calculate monthly interest.
6 For the twelve months ended November 30, 2012 there
7 was a net overcollection for the Demand- NGS and
8 Commodity components of purchased gas costs. Therefore,
9 the interest rate of 8°/o was used to calculate monthly interest.
10 The projection for the twelve month period ending November
11 30, 2013 is a net overcollection for the Demand - NGS and
12 Commodity components of purchased gas costs. Therefore,
13 the interest rate of 8% was used to calculate monthly interest.
14 Q. Please describe PGC Exhibit 21A.
15 A. PGC Exhibit 21 A is the Statement of
16 Over/Undercollections for the twelve months ended November
17 30, 2012. The exhibit provides separate detail for the
18 Commodity, Demand- NGS and Demand- DC components of
19 purchased gas costs, and the exhibit is self explanatory.

PGC Exhibit 21 8 is a calculation of interest on storage
injections and withdrawals. Sheet 1 shows the twelve months
ending July 31, 2013 and Sheet 2 shows the twelve months
ending July 31, 2014.
For base rate purposes, Distribution has valued gas in
storage at its average inventory cost. That is, withdrawals from
and injections into storage are priced at the average cost of all
gas in storage at the beginning of the gas storage cycle.
However, for purchased gas cost purposes, Distribution uses
the last-in, first-out ("LIFO") method. The LIFO method prices
withdrawals and injections at the average cost of all gas
purchases for the current year. The LIFO method is appropriate
for gas cost purposes because it recognizes that current
purchases of gas are used to serve current requirements and
that storage withdrawals used to serve peak requirements are
only short term and are refilled every year.
Over a normal twelve month period, withdrawals and
injections will be equivalent, and thus the beginning and ending
storage balances under the two methods will be the same.
However, Distribution recognizes that there is a time value of
money component to pricing storage gas at the average
Page 24 of 29
DIRECT TESTIMONY OF KAREN M. SNYDER R-2013-2341534
1 inventory cost, for working capital purposes in base rates. For
2 example, in a winter month, Distribution will be using storage
3 having an inventory value of $0. 7839/Mcf to serve peak
4 requirements, and will charge customers a higher, fiscal year
5 rate of $5.8012/Mcf for such gas. Conversely, in a summer
6 month, Distribution will refill storage using purchases priced at
7 $5.8012/Mcf, but the inventory value of these injections will be
8 the lower $0.7839/Mcf average inventory rate.
9 In order to recognize time value of money differences in
10 this 1307(f) proceeding, interest is calculated on storage
11 injections and withdrawals based upon the rate differential
12 between the storage rate and the inventory rate on a fiscal year
13 basis.
14 Q. Please summarize the calculation of interest shown on PGC
15 Exhibit 21 B.
16 A. PGC Exhibit 21 B, Sheets 1 and 2 show the interest
17 calculation for the twelve months ending July 31, 2013 and July
18 31, 2014, respectively. This calculation projects the estimated
19 interest to be incurred during the indicated PGC period. The
20 calculation, as detailed below, allows for immediate passback or
21 recovery on the basis of a uniform amount per Mcf during the
Page 25 of 29
DIRECT TESTIMONY OF KAREN M. SNYDER R-2013-2341534
1 current twelve month PGC period in which expense or income
2 arises. This methodology, as approved per the order at Docket
3 No. R-201 0-2150861, matches the occurrence of income or
4 expense with the reflection of such income or expense in rates.
5 In addition, this methodology allows for quarterly updates to the
6 estimated interest, based on actual information, through the C-
7 Factor gas cost recovery mechanism.
8 The net interest expense in the amount of $722,321 on
9 PGC Exhibit 21 B, Sheet 1 flows to Exhibit 21, Schedule 11,
1 o Sheet 4. This amount is compared to the total estimated
11 interest expense to be passed back during the twelve months
12 ending July 31, 2013 through the C-Factor. The difference
13 represents the estimated amount that will be included in theE-
14 Factor for the twelve months ending July 31, 2014.
15 PGC Exhibit 21 B, Sheet 2 shows the interest calculation
16 for the twelve months ending July 31, 2014. The calculation
17 shows an estimated net interest expense in the amount of
18 $139,480. This amount is projected to be passed back during
19 the rate application period in which it occurs, which is the twelve
20 months ending July 31, 2014. As shown on Sheet 2, the net
21 interest expense of $139,480 will be passed back at a rate of

($0.0075)/Mcf, included in the C-Factor on Exhibit 21, Schedule
1, Sheet 1.
Please explain the calculation of interest shown on PGC Exhibit
21 B, Sheet 2.
The schedule identifies months with estimated or actual data
as open or closed periods. Columns 1 and 2 show storage
injections and withdrawals. Column 3 shows the rate differential
which represents the difference between the storage inventory
rate included in base rates calculated on an average cost method
and the inventory rate charged through the 1307(f) gas cost
recovery mechanism based on the LIFO valuation method.
Storage injections represent decreases to purchased gas
expense as theoretically a portion of volumes purchased and paid
by Distribution exceed the current requirements. The Cost Paid
by Distribution but not Charged through the PGC, Column 5, is
calculated by multiplying the injections (column 1) by the rate
differential (column 3). These costs result in interest income to
be recovered from the ratepayer, as they will not be charged
through purchased gas costs until the gas is withdrawn. Storage
withdrawals represent increases to purchased gas expense, as
theoretically requirements exceed current purchases. The Cost
Page 27 of29
DIRECT TESTIMONY OF KAREN M. SNYDER R-2013-2341534
1 Charged through the PGC but not Paid by Distribution, Column 4,
2 is calculated by multiplying the withdrawals (column 2) by the rate
3 differential (column 3). These costs result in interest expense to
4 be passed back to the ratepayer, as they are charged through
5 purchased gas costs when the gas is withdrawn, but were paid by
6 Distribution when the gas was injected. Storage Net Paid/Net
7 Charged in Column 6 is the sum of columns 4 and 5.
8 The Interest Weight (column 7) represents the ratio of
9 the twelve month PGC period the interest is expected to be
10 outstanding. The Interest Rate (column 8) represents the
11 statutory rate to be charged for interest based on the estimated
12 net over/undercollection of associated storage costs for the
13 twelve months ended July. Column 9 represents the calculation
14 of gross storage interest expense or interest income. This is
15 calculated by multiplying the Storage Net Paid/Net Charged
16 (column 6) by the applicable prorated interest rate (column 7 x
17 column 8). The sum of the monthly values in column 9 (Gross
18 Storage Interest Expense/Revenue) represents the amount of
19 storage interest expense/income due to/from ratepayers.
